Primary non-Hodgkin's lymphoma (NHL) of the gastrointestinal tract is the most common extranodal NHL and accounts for 4%-20% of all NHL . Mantle cell lymphoma (MCL) comprises 2.5%-7% of all NHL . Gastrointestinal tract involvement occurred in 20% of MCL, which is commonly manifested as numerous, small, spherical, or hemispherical polyps, termed multiple(More)
BACKGROUND AND AIMS The American Association for the Study of Liver Disease issued guidelines that proposed that hepatocellular carcinoma (HCC) can be diagnosed if a mass is larger than 2 cm in a cirrhotic liver and shows typical features of HCC at triphasic liver computed tomography (CT) or dynamic magnetic resonance imaging (MRI). In non-cirrhotic livers,(More)
BACKGROUND The instrument channels of gastrointestinal (GI) endoscopes may be heavily contaminated with bacteria even after high-level disinfection (HLD). The British Society of Gastroenterology guidelines emphasize the benefits of manually brushing endoscope channels and using automated endoscope reprocessors (AERs) for disinfecting endoscopes. In this(More)
BACKGROUND Entecavir (ETV) is a potent inhibitor of viral replication in chronic hepatitis B. There is no published data concerning ETV therapy in nucleoside analogue (NUC)-naive hepatitis B surface antigen (HBsAg)-positive renal transplant recipients (RTRs). METHODS We prospectively treated 27 HBsAg-positive RTRs with ETV since 2007. Serial HBV DNA was(More)
BACKGROUND AND AIM There is limited data on the efficacy and outcome of telbivudine (LdT) therapy in patients with chronic hepatitis B and compensated cirrhosis. We evaluated LdT as first-line therapy in these patients and compared with those treated with entecavir (ETV). METHODS We consecutively enrolled 88 chronic hepatitis B patients with compensated(More)
AIM To conduct a bacterial culture study for monitoring decontamination of automated endoscope reprocessors (AERs) after high-level disinfection (HLD). METHODS From February 2006 to January 2011, authors conducted randomized consecutive sampling each month for 7 AERs. Authors collected a total of 420 swab cultures, including 300 cultures from 5(More)
BACKGROUND Inadequate reprocessing of double-balloon enteroscopy (DBE) or of endoscopic accessories may result in iatrogenic infections and present a risk to public health. AIM To use microbiological surveillance culture monitoring (SCM) to assess the adequacy of high-level disinfection (HLD) with standard reprocessing procedures of DBE. MATERIALS AND(More)
Pneumatic dilation (PD) is considered to be a safe and effective first line therapy for achalasia. The major adverse event caused by PD is esophageal perforation but an immediate gastrografin test may not always detect a perforation. It has been reported that delayed management of perforation for more than 24 h is associated with high mortality. Surgery is(More)
